+  # This option protects your application from creating new tokens before old valid one becomes

+  # Rationale: https://github.com/doorkeeper-gem/doorkeeper/issues/383
+  #
+  # You can not enable this option together with +hash_token_secrets+.
+  #
+  # reuse_access_token
+
+  # In case you enabled `reuse_access_token` option Doorkeeper will try to find matching
+  # token using `matching_token_for` Access Token API that searches for valid records
+  # in batches in order not to pollute the memory with all the database records. By default
+  # Doorkeeper uses batch size of 10 000 records. You can increase or decrease this value
+  # depending on your needs and server capabilities.
+  #
+  # token_lookup_batch_size 10_000
+
+  # Set a limit for token_reuse if using reuse_access_token option
+  #
+  # This option limits token_reusability to some extent.
+  # If not set then access_token will be reused unless it expires.
+  # Rationale: https://github.com/doorkeeper-gem/doorkeeper/issues/1189
+  #
+  # This option should be a percentage(i.e. (0,100])
+  #
+  # token_reuse_limit 100
+
+  # Only allow one valid access token obtained via client credentials
+  # per client. If a new access token is obtained before the old one
+  # expired, the old one gets revoked (disabled by default)
+  #
+  # When enabling this option, make sure that you do not expect multiple processes
+  # using the same credentials at the same time (e.g. web servers spanning
+  # multiple machines and/or processes).
+  #
+  # revoke_previous_client_credentials_token
+
+  # Hash access and refresh tokens before persisting them.
+  # This will disable the possibility to use +reuse_access_token+
+  # since plain values can no longer be retrieved.
+  #
+  # Note: If you are already a user of doorkeeper and have existing tokens
+  # in your installation, they will be invalid without adding 'fallback: :plain'.
+  #
+  # hash_token_secrets
+  # By default, token secrets will be hashed using the
+  # +Doorkeeper::Hashing::SHA256+ strategy.
+  #
+  # If you wish to use another hashing implementation, you can override
+  # this strategy as follows:
+  #
+  # hash_token_secrets using: '::Doorkeeper::Hashing::MyCustomHashImpl'
+  #
+  # Keep in mind that changing the hashing function will invalidate all existing
+  # secrets, if there are any.
+
+  # Hash application secrets before persisting them.
+  #
+  # hash_application_secrets
+  #
+  # By default, applications will be hashed
+  # with the +Doorkeeper::SecretStoring::SHA256+ strategy.
+  #
+  # If you wish to use bcrypt for application secret hashing, uncomment
+  # this line instead:
+  #
+  # hash_application_secrets using: '::Doorkeeper::SecretStoring::BCrypt'
+
+  # When the above option is enabled, and a hashed token or secret is not found,
+  # you can allow to fall back to another strategy. For users upgrading
+  # doorkeeper and wishing to enable hashing, you will probably want to enable
+  # the fallback to plain tokens.
+  #
+  # This will ensure that old access tokens and secrets
+  # will remain valid even if the hashing above is enabled.
+  #
+  # This can be done by adding 'fallback: plain', e.g. :
+  #
+  # hash_application_secrets using: '::Doorkeeper::SecretStoring::BCrypt', fallback: :plain
+
+  # Issue access tokens with refresh token (disabled by default), you may also
+  # pass a block which accepts `context` to customize when to give a refresh
+  # token or not. Similar to +custom_access_token_expires_in+, `context` has
+  # the following properties:
+  #
+  # `client` - the OAuth client application (see Doorkeeper::OAuth::Client)

+  # "implicit"           => Implicit Grant Flow
+  # "password"           => Resource Owner Password Credentials Grant Flow
+  # "client_credentials" => Client Credentials Grant Flow

+  #
+  #
+  grant_flows %w[authorization_code client_credentials password]
+
+  # Allows to customize OAuth grant flows that +each+ application support.
+  # You can configure a custom block (or use a class respond to `#call`) that must
+  # return `true` in case Application instance supports requested OAuth grant flow
+  # during the authorization request to the server. This configuration +doesn't+
+  # set flows per application, it only allows to check if application supports
+  # specific grant flow.
+  #
+  # For example you can add an additional database column to `oauth_applications` table,
+  # say `t.array :grant_flows, default: []`, and store allowed grant flows that can
+  # be used with this application there. Then when authorization requested Doorkeeper
+  # will call this block to check if specific Application (passed with client_id and/or
+  # client_secret) is allowed to perform the request for the specific grant type
+  # (authorization, password, client_credentials, etc).
+  #
+  # Example of the block:
+  #
+  #   ->(flow, client) { client.grant_flows.include?(flow) }
+  #
+  # In case this option invocation result is `false`, Doorkeeper server returns
+  # :unauthorized_client error and stops the request.
+  #
+  # @param allow_grant_flow_for_client [Proc] Block or any object respond to #call
+  # @return [Boolean] `true` if allow or `false` if forbid the request
+  #
+  # allow_grant_flow_for_client do |grant_flow, client|
+  #   # `grant_flows` is an Array column with grant
+  #   # flows that application supports
+  #
+  #   client.grant_flows.include?(grant_flow)
+  # end
+
+  # If you need arbitrary Resource Owner-Client authorization you can enable this option
+  # and implement the check your need. Config option must respond to #call and return
+  # true in case resource owner authorized for the specific application or false in other
+  # cases.
+  #
+  # Be default all Resource Owners are authorized to any Client (application).
+  #
+  # authorize_resource_owner_for_client do |client, resource_owner|
+  #   resource_owner.admin? || client.owners_allowlist.include?(resource_owner)
+  # end
+
+  # Hook into the strategies' request & response life-cycle in case your
+  # application needs advanced customization or logging:
+  #
+  # before_successful_strategy_response do |request|
+  #   puts "BEFORE HOOK FIRED! #{request}"
+  # end
+  #
+  # after_successful_strategy_response do |request, response|
+  #   puts "AFTER HOOK FIRED! #{request}, #{response}"
+  # end
+
+  # Hook into Authorization flow in order to implement Single Sign Out
+  # or add any other functionality. Inside the block you have an access
+  # to `controller` (authorizations controller instance) and `context`
+  # (Doorkeeper::OAuth::Hooks::Context instance) which provides pre auth
+  # or auth objects with issued token based on hook type (before or after).
+  #
+  # before_successful_authorization do |controller, context|
+  #   Rails.logger.info(controller.request.params.inspect)
+  #
+  #   Rails.logger.info(context.pre_auth.inspect)
+  # end
+  #
+  # after_successful_authorization do |controller, context|
+  #   controller.session[:logout_urls] <<
+  #     Doorkeeper::Application
+  #       .find_by(controller.request.params.slice(:redirect_uri))
+  #       .logout_uri
+  #
+  #   Rails.logger.info(context.auth.inspect)
+  #   Rails.logger.info(context.issued_token)
+  # end
+
+  # Under some circumstances you might want to have applications auto-approved,
+  # so that the user skips the authorization step.
+  # For example if dealing with a trusted application.
+  #
+  # skip_authorization do |resource_owner, client|
+  #   client.superapp? or resource_owner.admin?
+  # end
+
+  # Configure custom constraints for the Token Introspection request.
+  # By default this configuration option allows to introspect a token by another
+  # token of the same application, OR to introspect the token that belongs to
+  # authorized client (from authenticated client) OR when token doesn't
+  # belong to any client (public token). Otherwise requester has no access to the
+  # introspection and it will return response as stated in the RFC.
+  #
+  # Block arguments:
+  #
+  # @param token [Doorkeeper::AccessToken]
+  #   token to be introspected
+  #
+  # @param authorized_client [Doorkeeper::Application]
+  #   authorized client (if request is authorized using Basic auth with
+  #   Client Credentials for example)
+  #
+  # @param authorized_token [Doorkeeper::AccessToken]
+  #   Bearer token used to authorize the request
+  #
+  # In case the block returns `nil` or `false` introspection responses with 401 status code
+  # when using authorized token to introspect, or you'll get 200 with { "active": false } body
+  # when using authorized client to introspect as stated in the
+  # RFC 7662 section 2.2. Introspection Response.
+  #
+  # Using with caution:
+  # Keep in mind that these three parameters pass to block can be nil as following case:
+  #  `authorized_client` is nil if and only if `authorized_token` is present, and vice versa.
+  #  `token` will be nil if and only if `authorized_token` is present.
+  # So remember to use `&` or check if it is present before calling method on
+  # them to make sure you doesn't get NoMethodError exception.
+  #
+  # You can define your custom check:
+  #
+  # allow_token_introspection do |token, authorized_client, authorized_token|
+  #   if authorized_token
+  #     # customize: require `introspection` scope
+  #     authorized_token.application == token&.application ||
+  #       authorized_token.scopes.include?("introspection")
+  #   elsif token.application
+  #     # `protected_resource` is a new database boolean column, for example
+  #     authorized_client == token.application || authorized_client.protected_resource?
+  #   else
+  #     # public token (when token.application is nil, token doesn't belong to any application)
+  #     true
+  #   end
+  # end
+  #
+  # Or you can completely disable any token introspection:
+  #
+  # allow_token_introspection false
+  #
+  # If you need to block the request at all, then configure your routes.rb or web-server
+  # like nginx to forbid the request.
